Lab 8: Benchmarking Message Passing
Due: 5:00 PM, Friday, November 7, 2008

A relatively short lab assignment this week to allow sufficient time to work on your final project proposal.

Write the program described in Exercise 6.8 of Quinn. Run your program within these MPI environments to estimate their bandwidths and latencies:

  1. Two processes running on the head node of our cluster.
  2. Two processes running on different FreeBSD nodes of our cluster.
  3. Two processes running on the 4-processor FreeBSD node, wetteland.
  4. Two processes running on different Solaris nodes in our cluster, bullpen and wetteland.
  5. Two processes running on different Solaris nodes at RPI's WCL.
  6. Two processes running on different AIX nodes at RPI's WCL.

Submit your programs and a document analyzing the results as lab8 using the turnin utility.
